The purposes of this study were to examine the two processes of social comparison and self-comparison, and to suggest the applications of social comparison theories and self-comparison theories. For these purposes, social comparison theory, self-evaluation maintenance model, control theory, self-discrepancy theory, regulatory focus theory, and temporal comparison theory were reviewed. The processes of social comparison and self-comparison are different, but both comparisons are similar in that they have some effects on self-evaluation, emotion, motivation and behaviors. Suggestions on education, health, economic justice and interpersonal relationships were discussed.

As the degree of economic development of society increases, the maintenance issues on the existing social overhead capital becomes essential. Accordingly, the adaptation of the concept of Level of service in highway maintenance is indispensable. It is also crucial to manage and perform the service level such as road assets to provide universal services to users. In this regards, the purpose of this study is to improve the maintenance service rating model and to focus on the assessment items and weights among the improvements. Particularly, in determining weights, an Analytic Hierarchy Process (AHP) is performed based on the survey response results. After then, this study conducts unsupervised neural network models such as Self-Organizing Map (SOM) and Davies-Bouldin (DB) Index to divide proper sub-groups and determine priorities. This paper identifies similar cases by grouping the results of the responses based on the similarity of the survey responses. This can effectively support decision making in general situations where many evaluation factors need to be considered at once, resulting in reasonable policy decisions. It is the process of using advanced technology to find optimized management methods for maintenance.

Recently, study on self-healing materials have been performed to increase the life by repairing the damage of structures themselves, which are difficult to repair or require high maintenance costs. A water permeability test has been widely used for the evaluation of self-healing performance. However, in the self-healing performance test method, the initial crack width of the concrete greatly affects on the self-healing performance but it does not have a consistent standard. Therefore, in this study, the correlation between crack and permeability and that between time and permeability were analyzed based on crack width and permeability. In addition, since the initial crack width measured by optical microscope is not reliable, the value is derived from the Poiseuille flow and the tendency of time-permeability and time-crack width are analyzed.

Purpose: The purpose of this study was to identify change in the exercise behavior and to identify factors influencing long-term adherence to aquatic exercise in patients with arthritis as a follow-up study after five years. Method: Baseline data had been collected using a structured interview 6 months after participants completed the aquatic exercise educational program. This second follow-up data collection included 133 participants from the original baseline study and was done 5 years after the original baseline study. Data was analyzed using SPSS 16 Win program. Results: The stage of change for the participants was as follows: Precontemplation (44.3%), Contemplation (24.1%), Preparation (3.0%), Action (0%) and Maintenance (adherence, 28.6%). The adherers (N=38) had significantly higher scores than non-adherers (N=91) in self-efficacy, outcome expectancy, group coherence and self-evaluation, and significantly lower scores in barriers to exercise. In logistic regression analysis, self-efficacy, group cohesion, barriers to exercise and self-evaluation were associated with exercise adherence (Chi Square=17.14, p=.002). Group cohesion (OR=2.5871, 95% CI=1.094-6.113, p= .030) was the most important factor. Conclusion: Self-efficacy, group cohesion, barriers to exercise and self-evaluation need to be considered in planning exercise programs to improve exercise adherence.

Concrete undergoes various deterioration on surface. Impregnant with silicate is usually applied to concrete surface and forms insoluble hydrates, which can provide many engineering advantages. In the work, concrete impregnated with colloidal silicate is used for durability enhancement in surface and self-clearing performance is evaluated with photocatalyst-$TiO_2$ spraying. For the work, various tests are performed both for strength evaluation and durability evaluation such as absorption ratio, drying shrinkage, chloride penetration, sulfate resistance, and freezing/ thawing action. Furthermore, removal and self-clearing performance are evaluated with Acetaldehyde decomposition and Methylene blue decolorization. Through silicate impregnation and photocatalyst spraying, the impregnated concrete can have not only durability enhance but also self-clearing performance.

In this study, the self-healing performance of mortar beams containing self-healing materials was evaluated through experiments. Normal mortar beams and self-healing mortar beams were used In the experiments. The self-healing performance was evaluated by comparing the mortar compressive strength, member strength, and self-healing effects of cracks. The experimental results showed that the compressive strength of mortar containing self-healing material was smaller than that of normal mortar, but the ratio of 118 days compressive strength to 28 days compressive strength was the same. The member strength tended to increase with increasing curing period. In normal mortar specimens, the member strength did not recover even if the curing period increased, but the strength of the self-healing mortar specimens tended to recover as reaction products were produced. The crack width tended to decrease after the healing periods in both specimens, but the reaction product was observed only in the self-healing mortar specimens.

In this study, self - healing microcapsules which can be mixed directly with cement composites were prepared, and the quality and crack healing performance of cement composites with self - healing microcapsules were evaluated. In the past, it has been focused on evaluating self-healing capsules and crack healing properties. Therefore, self - healing microcapsules have been studied for their effect on the quality of cement composites when mixed with cement composites. The table flow and the air flow rate of the cement composite material mixed with self-healing microcapsules were found to have no significant influence on table flow and air volume regardless of mixing ratio. Compressive strength and splitting tensile strength tended to decrease with increasing capsule mixing ratio. As a result of evaluation of crack healing properties according to water flow, initial water permeability decreased, and reaction products were generated over time and cracks were healed.

Purpose: The purpose of this research was to develop and train caregivers in tracheostomy tube care using a self-management program to assist patients with an 'at home' tracheostomy procedure. Caregivers' self-efficacy and knowledge of tracheostomy management before and after the training was also identified. Methods: Research participants were the main caregivers for patients with tracheostomies who were affiliated with a 'Home Healthcare Center'. Training and observation were done at 'A Hospital' and 'G Hospital' both affiliated with 'K University' in Seoul. Data were collected from May 3, 2010 to January 25, 2011 and analyzed using Wilcoxon signed rank test with SPSS program version 12.0. Results: Significant differences were found for the pre and post evaluation of the 'self-management program' for the implementation of tracheostomy care. The development and implementation of the 'self-management program' improved the main caregivers' knowledge of tracheostomy tube management (Z=-3.599, p<.001). Conclusion: Results show that this program has identified an effective nursing intervention for promoting the caregivers' knowledge of tracheostomy care and self-efficacy. We recommend that further research should be done to test primary caregivers' maintenance of knowledge and self-efficacy in tracheostomy tube management and identify factors affecting knowledge and self-efficacy in the care of these patients.
